Pivoting Cross-Wire Feeder for Lower Magazine Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing fence mats with cross wires above and below longitudinal wires result in inefficiencies due to excessive longitudinal wire usage, leading to significant downtimes and increased costs associated with investment, maintenance, and setup, particularly because of the need for complex electrical drive technology and additional space for cross-wire magazines.
Innovation Solution
A cross-wire feeder designed as a pivoting switch that can be positioned to either feed cross wires directly to the production line or load a lower cross-wire storage, allowing for efficient use of downtimes to fill and maintain the storage, reducing the need for multiple magazines and complex drive systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two cross wire magazines are arranged (one above and one below the production line) to enable double wire fence panel production, then cross wire feeding capability is improved, but device complexity and space requirements increase significantly
Solution Approach 1:
The single cross-wire magazine is designed to serve dual purposes: feeding cross wires to the upper cross-wire feeder during production, and serving as a storage magazine during downtime. This multi-functional design eliminates the need for separate storage magazines above and below the production line, reducing device complexity while maintaining full feeding capability.
Solution Approach 2:
The invention merges the functions of the upper and lower cross-wire magazines into a single magazine located above the production line. The magazine simultaneously supplies both the upper cross-wire feeder (during production) and serves as a storage reservoir, combining what were previously separate components into one integrated system.
2Measurement precision
If complex electric drive technology is used to position cross wire magazines below and to the side of the production line, then positioning accuracy is improved, but investment and maintenance costs increase
Solution Approach 1:
The invention extracts and eliminates the complex electric drive technology from the system by repositioning the cross-wire magazine to a location (above the production line) where simple gravity-based feeding is sufficient. This removes the need for costly positioning mechanisms while maintaining adequate feeding functionality.
Solution Approach 2:
The invention replaces expensive, complex electric drive positioning systems with simple, low-cost gravity-based feeding mechanisms. The cross-wire magazine and feeders are positioned to utilize natural gravity flow, eliminating the need for motorized positioning while maintaining operational effectiveness.
3Area of stationary object
If cross wire magazines are positioned below and to the side of the production line, then space utilization is improved, but additional space requirements and complex transport devices are needed
Solution Approach 1:
Instead of positioning the cross-wire magazine below and to the side of the production line (conventional approach), the invention inverts the arrangement by placing the magazine above the production line. This inversion eliminates the need for complex downward transport mechanisms and allows direct gravity-based feeding to both upper and lower cross-wire feeders.
4Adaptability or versatility
If two cross wire magazines are used for double wire fence panel production, then production versatility is improved, but downtime between panels increases due to retooling
Solution Approach 1:
The single cross-wire magazine is designed to universally supply both upper and lower cross-wire feeders, allowing the system to produce various fence panel configurations (single wire, double wire, stacked panels) without requiring physical retooling or changing of magazines. The universal magazine maintains continuous stock availability for different production modes.
Solution Approach 2:
The cross-wire magazine is pre-filled with cross wires during downtime periods, preparing the system for immediate resumption of production. This preliminary stocking action eliminates the need for retooling or magazine changes when transitioning between production modes, as the single magazine is designed to supply all feeding requirements.
